✨ Trivia
Handle with care
🛡️What 'hazardous' means. 'Potentially hazardous' is bookkeeping, not a prediction: it means the orbit passes within 0.05 AU of Earth's and the body is big enough to matter. Nothing on that list is known to be on a collision course.
☄️If it ever hit. A rock this size arriving at a typical 20 km/s would release around 656 megatons — about 13.1 times the largest bomb ever detonated.
What it actually is
🛸Its orbit family. An Aten-class object, spending most of its time inside Earth's orbit and crossing ours from the sunward side — which makes this family wretchedly hard to spot against the daylight.
🌞Closest approach. At its nearest it comes within 0.74 AU of the Sun — inside the orbit of Earth.
🔁One lap. A single orbit around the Sun takes it about 345 days.
🥏How far it roams. Its orbit swings between 0.74 and 1.19 AU from the Sun.
Sense of scale
🧱Sense of scale. In everyday terms it is about 2.1 football pitches across.
Standing on it
🦘Don't jump. Escape velocity here is only around 0.13 m/s. A determined jump would launch you off it and into your own orbit around the Sun.

Why (487577) 2014 YQ15 is an uncommon neo
(487577) 2014 YQ15 scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 3 points would lift it into a rarer tier.
That score comes from 4 science badges — Near-Earth object, Catalogue designation only, Aten: mostly inside Earth's orbit and Passes within two lunar distances of Earth's orbit — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
